[Isolated and combined occlusion of the cilioretinal artery and the central retinal vein].

Cilioretinal artery occlusion is rare pathological condition because of infrequent occurrence of the cilioretinal artery in the human retina. It presents as an isolated entity, or as a combined cilioretinal artery--central retinal vascular, mostly venous occlusion. Authors present the course, angiographic features, prognosis, risk factors and final outcome of the isolated cilioretinal artery occlusion and combined cilioretinal artery--central retinal vein occlusion. Occlusion of the cilioretinal artery is believed to result from obstruction of the central retinal vein, as a primary process, in the case of combined cilioretinal artery--central retinal vein occlusion.
